ELECTRIC-LINE INSULATOR.

To all whom it may concern.

'Be it known that 1, ROBERT HENRY, a citizen of the United States, and a resident of Pueblo, in the county of Pueblo and State of Colorado, have invented a new and useful Improvement in Electric-Line Insulators, of which the following is a specification.

My invention relates to improvements in the method of insulating electric lines on poles in tached to the usual pin and a peculiar form is given for holding the. line firmly in 'position: and the objects of my invention are; lirst, to provide a means for holding the line or cahle in position without the use of bindingwires; second, to provide a rapid means of attaching the line to the insulator; third, to furnish additional strength in the insulator; and fourth, to provide such insulator with means of ready repair in case of acci dent or quick facilities of change of line. I attain these objects by the mechanisms illustrated in the accompanying drawings in which,-

Figure 1' is a perpendicular sectional View;

Fig. is a plan view with broken section of one arm; Fig. is a perspective view; .and Fig. 4 is a side view of the locking pin.

Similar numerals refer to similar parts throughout the several views.

The ordinary pin or post- 1. with threads 8 is used. A cap 2, threaded to lit post 1, is constructed of any well known insulating, material, glass icing preferred. The upper portion of cap 2 is threaded as at 7 down to a point opposite the threads on 1 and is made in one solid piece covering the top ol 1, the cap 2 hclng threaded intcriorlv to fit post 1 and cxteriorly as stated. A locking cap 3 having interior threads 7 fitting exterior threads on 2 is constructed withcxtending bosses 1.; and arch of said ho'sses has a lateral slot and a pcrpcndicular slot 4; so placed that the slot 5 extends a'required distance in past the-interior side of lforining pocket-4f. Said locking cap is also provided with extended, tlangcd base 12, and so adjusted as to leave a space 14 between 2 and lower parts of 3. Locking key 9, Fig. 4, is provided which [its into perpeinlicular slot l. At the lower end of locking key 9 angular space 10 is pmvided the usect which is explained further on. The line 'or wire is represented by 11.

which the insulating material is at- Specification of Letters Patent.

Application filed October 5, 1908.

circular base and extended portion of Patented May 25, 1909. Serial No. 468,198.

The device being adjusted upon nin or post 1 a wire or line 11 is passed into slot 5 and locking pin 9 is inserted in slot 4.- and firmly driven in and thereby kinks the line or wire ll as shown at 11' In this form theinsulation is h the space 14. which completely encircles I2 and the wire 11 by the clamp or kink at 11 is firmly held in position.

if desired two wires may be placed on each insulator, one in each of the slots 5, or upon accident or injury to one of the bossesthe other is available for use in repairing. The pull of the line or wire upon the insulator is made by the construction to hear equally upon that portion of the pin 1 included in the insulator. The notch 10 in locking pin 9 is n'ovided as a means of removing pin when desired by use of a punch through space 14.

I claim:

1. In an electric line insulator ol the character descrihed, an interiorscrew threaded locking on titted on interior insulation e);- a I terror bosses on said locking cap each having a perpendicular slot, a pin litted in said perpeinlicular slot having a notch in the lower end, a lateral slot in each of mid bosses intersccting said perpendicular slot and making pocket on interior side of said perpendicular slot, flanged circular base on said locking cap, a space between said flanged circular base and extended portion of interior insulation, all substantially as set forth.

2. In an electric line insulator of the character descrihed, an interior screw threaded locking cap titted on interior insulation, exterior bosses on said locking cap each having a perpendicular slot, 5). pin fitted in said perpendicula r slot having a notch in the lower end, -a lateral slot in each of said bosses intersecting' said perpendicular slot and making pocket on interior side of said perpendicular slot, flanged circular base on said locking cap, a space between said flanged interior insulation, interior insulation screw threaded on interior and screw threaded on exterior to lit interior 01' said locking cap, all

substantiallv as set forth.
